FINGER-CUFF.

Specification of Letters Patent.

Patented Oct. 22, 1912.

Application filed January 20, 1912. Serial No. 672,303.

To all whom it may concern:

Be it known that I, CLARENCE CLINTON :HEDRICK, a citizen of the United States, and a resident of Kansas City, in the county of lVyandotte and State of Kansas, have invented a new and Improved Finger-Cuff, of which the following is a full, clear, and exact description.

My invention relates generally to finger cuffs and more particularly it comprehends a shackle of new and improved construction which is adapted to be secured on any finger of either hand, the device being especially intended to prevent escape.

The principal object of the invention is to provide a new and improved shackle or finger cuff made up of parts in which the finger is positioned, the parts being movable relatively to each other and being adapted to be held in such removed position whereby movement of the finger or straightening thereof is prevented.

A further objectof the invention is to provide a new and improved finger cufli' adapted to be positioned on any finger of either hand, the cuff comprehending a pair of devices secured together whereby persons may be shackled together in order to prevent their escape.

Other objects and advantages of the invention will appear as the description thereof proceeds, all of which is particularly pointed out and included in the appended claims.

Reference is to be had to the accompanying drawings forming a part of this specification in which similar characters of reference denote corresponding parts in all the views, and in which Figure 1 is a perspective view of the device in operative position on the index finger; Fig. 2 is a vertical sectional view of the device showing the little finger disposed therein previous to bending; Fig. 3 is a similar view showing the position of the finger after the parts of the device have been moved relatively to each other; Fig. 4c is a similar view showing another finger positioned within the device previous to movement of the parts; Fig. 5 is a view showing the parts of Fig. 4 after having been moved.

The device herein shown and described is capable of many modifications as to size and finish as well as the material of which it is made, it being clear that such features or details of construction may be variously made in a multitude of devices each of which embodies the spirit of my invention Without departing from such invention.

As shown particularly in Figs. 2 and 3 the finger cuff comprises two curved elements 1, 2, the side portions of each being in pivotal engagement by means of a suitable pin 3 extending through suitable openings in these side portions. One of the portions 2 is preferably provided with a hook & whereby any suitable chain or equivalent device 5 may be secured thereto in order to hold two of the cuffs secured together at a suitable distance. Positioned within the element 2 and pivotally mounted on the pin 3 is a third curved element 6 movable relatively to the element 2 about the pin 3, this third element being adapted to be moved to a variety of positions, one of which is indi-. cated in Fig. 2 of the drawings. One side of the element 2 on the exterior thereof is preferably provided with a suitable plate 7 secured thereto by being attached to one end of the pin 3, the other end of the plate being held in position on this element by suitable means, such as rivets or bolts 8. Referring particularly to Fig.- 1 it will be noted that one side portion of the element 1 is provided with anumber of serrations 9, preferably arranged on the arc of a circle, while a suitable dog 10 is positioned be tween the plate 7 and the element 2, the dog being adapted for engagement in any one of the serrations 9, being held in such position, preferably by means of a leaf spring 11. The plate 7 is preferably provided with a slot 12 whereby a suitable key may be entered into engagement with the pawl 10 in order to bring it out of engagement with any one of the serrations 9, such construction being preferable, although it is clear that any suitable form of locking device may be used to retain the parts in the position shown in Fig. 1. When the elements 1 and 2 are brought into the position shown in Fig. 2 and the third element 6 is included wholly within the element 2, as shown, a finger of small size may be inserted into the elements, after which the element 2 and also the element 6 may be turned aboutthe pin 3 into the position shown in Fig. 3, locking of the parts in such position preventing withdrawal of the finger therefrom, the finger being held in a bent position. In order to provide a convenient bearing for the finger and to prevent cutting thereof, the pin 3 is preferably provided with an extended bearing surface through the mediumof a member 13 positioned on the pin, adapted for engagement with the finger, as shown I bent finger. From what hasbeen said it will appear that the third element 6 may be used in different positions, the purpose of the element in any position being to properly aid in .securing the finger within-the cuff;

in the position shown in Figs. 1 to 3 in-- elusive the third element, by being entered into the element 2, provides for the use of the device on small fingers; in the position shown in Figs. 4 and. 5, it prevents unduemovement of the elements 1 and '2 when in locked position, thereby avoiding injury to the finger since'it prevents further articula-' tion thereof, such position also preventing movement of the'finger in order that it may be freed from .the cuff; Thus the device is of such size that it maybe used onwfingers' differing in size, thereby making it available for wide use. In order to return the parts to normal position, thereby permitting the finger to be withdrawn, a suitablekey may be inserted in the slot 12 whereby the dog l0 may be brought out of engagement with the serrations 9,"after which theelement 2 may be turned about the pin 3,"the finger being easily withdrawn when theparts come into; the position shown in Figs. 2 and 4.

It is obvious that in place of the particu-. lar locking means which I have'shown, Va rious other devices may be employed, the object of any of which is to prevent relative movement of the parts of the device, in order to prevent withdrawal of the-fin-' ger therefrom,"thereby preventing the es;

cape of persons whose hands are shackled or persons who are shackled together.

Having thus described my invention, I claim as new,'and desire to secure by Letters Patent 1- 1..A device of'the class described, comprising a plurality of curved elements in pivotal relationwith each other, the said elements being adapted to be positioned one within the other or one with'outthe other, together with'means for holding'lthe elements secured against relative movement-in such last mentioned position;
